Israeli warplanes on Thursday targeted a house in the southern border town of Blida, the National News Agency said.
“Ambulance crews are heading to the location,” NNA added.
An Israeli drone had earlier bombed a home on the eastern outskirts of Markaba.
Hezbollah meanwhile announced fresh attacks on Israeli posts and troops, saying it attacked the Malkia, al-Marj and Hanita positions.
It also announced an overnight attack on an Israeli force that was trying to remove a targeted military vehicle from the Metula post. The new attack caused “certain casualties,” Hezbollah added.
It had announced the death of two of its fighters overnight in the town of Kfarkela.
Israel and Hezbollah have been exchanging near-daily cross-border fire since Israel started its war on Gaza.
The violence has killed at least 368 people in Lebanon, mostly Hezbollah fighters but also at least 70 civilians, according to an AFP tally.
